6BRA load data
- Thread starter Alex Wheeler
- Start date
I have a couple of good loads which are all much a muchness when I do my part. Barrel is a 30" Krieger, 1:8 twist, parallel, .237 bore, 5R. 31.2gr of RL15 and Berger 105gr VLDs (10 thou jam) shoots very well - around 2980fps. 30gr of 4895 with Berger 108s (jumped 10 thou) also shoots very well, velocity around 2970fps.
Fclass gun...Varget...Sierra 107's....Russian primers .012 off touch...don't own a chronograph. 3" spotter 606yrds.

Damn Norm, pics like that make me want to shoot an open gun.
31.2 grains of R15 is giving you 2980? That's a pretty fast barrel...

I had a .237 4 groove Krieger straight 1.25 28” chambered up with .104 freebore. .271 neck and I turn to .012 neck wall. I use a .265 bushing then go back with 21st century mandrel to iron out. FF load I used 29.2 grains of varget with the 105 VLD 15k into the lands. Fun to shoot 2.5-3” inch groups at 600 yards.
FF at 600 with the above load.
Ladder test at 1000 that agreed with all of the load testing I was running once I switched to the 108 that I targeted as my match bullet. I shoot Fclass it’s extremely fun cartridge to shoot. Match load is 30.54 behind the Berger 108’s slight jam .007 into the lands. Load now shoots in the 2920’s now that I have several hundred rounds on this barrel.

6BRA,103 VT, .005 jam, 31.5 of varget;
At 500 yds its printing 1"- 5 shot groups[/QUOTE]
31.2 is now at 2941
31.5 is now at 2965
Barrel is a 26.5" 1-7.75 Brux with 625 rnds thru it.
.005 in and .005 off seem to both shoot well.

That's my plan as well Johnny (as soon as my rifle gets here). Good shooting

.236 Krieger 12TW HV @ 28" with Alex's 2.0 chamber on a Panda...
It's about got me convinced that this is the load:
80gr Precision Ballistics 8 Ogive BT
33.0gr XBR8208 - normal disclaimers apply. Mine has a long freebore for such a short BT bullet.
Tula SRM
Lots of neck tension (.265" loaded neck for .268 chamber, .261" bushing, then a .2395" mandrel for good measure - it barely touches unless there's something goofy with a case)
.005" off touch
3,350 FPS
This is on a 4" LRB with the scope mounted way up high for free recoil. Practically shoots itself. It shot so well at a 300 yard match that I tried it for three relays at our 500M Fly Shoot (I should have stopped at 2, as conditions deteriorated). I'm not up to the task of knowing where to point it at 500M, and that was never my intention when I built it. However, I am convinced it could win at that distance in more capable hands (or under ideal conditions).
It's definitely on the zippy side. I have had to keep a close eye on my loads as I have steadily had to drop them to stay in the 2960-2990 zone. I did run into serious pressure issues running 30.4gr of 4895 with the Berger 108s. 30.2gr and my Labradar still showed them moving at 2985fps so I've since dropped it to 30gr flat. RL15 hasn't given me the same pressure issues but I'm mainly running 105s with it.
The 30” barrel may be helping with a little more speed also.

Pretty sure they have a shoot this Sunday as well, a friend told me about it.
No need to apologize, the shoot on 4/28 only had 8 shooters, not many people made it,.....That's probably why I was competitive. I wont be able to make the groundhog shoot this weekend, I have a business trip to a Logging show in Vermont.
Rimersburg shoots are always on Sundays at 9:00. First 100,300 and 500 was on 4/22.
The 1st 100,200 and 300 was on 4/29.
Is anyone shooting 115 dtacs in their BRA?
